Stephen Ames won the Principal Charity Classic on Sunday for his second PGA Tour Champions title, taking advantage of Tim Herron's final-round collapse.
Seven strokes behind Herron entering the round, Ames shot a 5-under 67 for a one-stroke victory over fellow Canadian Mike Weir.
A four-time winner on the PGA Tour, Ames won the 2017 Mitsubishi Electric Classic for his first senior title. The 57-year-old naturalized Canadian citizen from Trinidad finished at 12-under 204 at Wakonda Club.

Weir closed with a 69.
Herron bogeyed three of the final five holes in a 76 that left him tied for third at 10 under. He missed a chance for his first senior victory after winning four times on the PGA Tour.
Willie Wood (68) and Doug Barron (71) matched Herron at 10 under.
